dd.plot {depth.plot}

Depth-Depth Plots

Description

dd.plot is a multivariate genralization of a normal QQ-plot. It produces a DD-plot of two datasets.

Usage

dd.plot(data1, data2 = rmvnorm(nrow(data1), array(0, ncol(data1)), diag(1,
  ncol(data1), ncol(data1))), main = "Normal DD-plot",
  xlab = "Sample Depths", ylab = "Normal Depths", col = "black",
  pch = 20)

Arguments

data1

A matrix or a data.frame with each row as a p-variate observation.

data2

A matrix or a data.frame (defaults to a standard independent p-variate normal).

main

Plot labels. The title of the plot.

xlab

Plot labels. The x-axis label of the plot.

ylab

Plot labels. The y-axis label of the plot.

col

The color of the points

pch
